摘　　要：寡头垄断市场是微观经济学研究的重要内容,由于一个寡头市场中存在寡头厂商可能不止两家的情况,研究三寡头厂商关于产量的非合作博弈有理论和实际意义.针对产量连续变动情形,给出了三寡头厂商基于Cournot模型的同时决策博弈,基于Stackelberg模型的三阶段序贯决策博弈和序贯决策博弈结合同时决策博弈的两阶段博弈,得出了相应的纳什均衡解和逆向归纳解.对四种博弈结果做了简化的比较,由此可以看出各种博弈对寡头厂商产量决策影响的变化.Oligopolistic markets are an important aspect of microeconomic research.Because there may be more than two oligarchs in an oligarchic market,it is of theoretical and practical significance to study the non cooperative game of three oligarch firms on output.The simultaneous decision game based on Cournot model and the three stage sequential decision game based on Stackelberg model,and the two-stage game of sequential decision game combined with a simultaneous decision game of three oligarch firms in the case of continuous changes in production are given.The corresponding Nash equilibrium solution and inverse inductive solution are obtained.A simplified comparison of the results of the four games is made,from this,it can be seen that various games have varying impacts on the output decisions of oligopolistic manufacturers.
